    An initially stationary box on a frictionless floor explodes into two pieces, piece A with mass m^ and piece B with mass \[{{m}_{B}}\]. Two pieces then move across the floor along x-axis. Graph of position versus time for the two pieces are-given.
    (I)   (II) (III)
    (IV) (V) (VI)
    Which graphs pertain to physically possible explosions -

    A) II, IV and V              

    B) I, III, VI

    C) I, II, V                 

    D) II, III, VI

    Correct Answer: A

    Solution :

    Physically possible explosions are those in which both particles move in opposite directions, i.e. signs of velocities are opposite \[\Rightarrow \] II, IV & V
